General Pink 95% Alumina Ceramic Tube Overview
The pink ceramic tubes are high-performance technical ceramic components manufactured from 95% aluminum oxide (Al₂O₃). They offer excellent electrical insulation, high-temperature resistance, wear resistance, and chemical stability, making them ideal for demanding industrial and electrical applications.
This standard ceramic tube features an outer diameter of 6 mm, inner diameter of 3.5 mm, and length of 50 mm. The pink appearance is a common characteristic of 95% alumina ceramics due to trace additives used during manufacturing.
The schematic diagram of the ceramic tube is as follows:
This standard product has a slightly larger tolerance by default, which is due to a comprehensive consideration of factors such as cost and applicability. It is directly hot-pressed and sintered without any additional secondary processing. If you have customized tolerances or surface finish requirements, we can certainly do that too.
Key Features for Alumina Ceramic Tubes
Alumina is one of the most widely used materials for ceramic tubes due to its excellent overall performance. Compared with metal tubes and plastic tubes, alumina ceramic tubes offer superior performance in harsh operating environments.
95% alumina ceramic provides reliable insulation under high voltage and high-temperature conditions.
Suitable for continuous operation in elevated temperature environments.
The high hardness of alumina ceramic helps reduce wear and extend service life.
Resistant to most acids, alkalis, and chemical environments.
Maintains stable dimensions under thermal and mechanical loads.

A 95% alumina ceramic tube is an industrial ceramic component manufactured primarily from aluminum oxide. It offers excellent electrical insulation, wear resistance, and thermal stability, making it suitable for electrical, mechanical, and high-temperature applications where conventional materials may fail.
The pink color commonly found in 95% alumina ceramic tubes results from trace additives used during ceramic manufacturing. These additives help optimize sintering performance and material properties. The color does not negatively affect the mechanical, thermal, or electrical performance of the ceramic tube.
Yes. Alumina ceramic tubes are widely used in high-temperature applications because they maintain mechanical strength and dimensional stability under elevated temperatures. They are commonly found in heating equipment, thermocouple protection systems, and industrial furnaces.
Yes. Alumina ceramic tubes can be precision machined after sintering using diamond grinding processes. Operations such as diameter grinding, length trimming, polishing, and tight-tolerance finishing can be performed according to application requirements.
Yes. Custom ceramic tubes can be produced in various diameters, lengths, wall thicknesses, and surface finishes. Additional services such as precision machining, metallization, and assembly support are also available according to customer specifications.
